In Canada’s construction industry, risk doesn’t just come from complex builds or tight timelines—it often comes from something far more ordinary: materials. Whether it’s custom windows, HVAC units, or high-end appliances, materials in transit or sitting on a job site can represent significant financial exposure.
This article breaks down how builder’s risk insurance works in Canada, who is responsible for materials at different stages, and what contractors and developers can do to reduce theft, damage, and liability.
What Is Builder’s Risk Insurance?
Builder’s risk insurance (also called course of construction insurance) is a specialized policy designed to cover property damage during construction projects. In Canada, it is commonly purchased by:
- Property owners
- General contractors
- Developers
What It Typically Covers
A standard Canadian builder’s risk policy may include:
- Buildings under construction
- On-site materials and supplies
- Temporary structures (e.g., scaffolding)
- Materials in transit (sometimes limited)
- Soft costs (optional add-ons like delay expenses)
Common Covered Risks
- Fire and explosions
- Theft and vandalism
- Weather-related damage (depending on policy wording)
- Accidental damage during construction
The Critical Gap: Material Storage & Transit Risks
While builder’s risk insurance provides broad protection, coverage is not unlimited or automatic—especially when it comes to materials.
1. Materials in Transit
Coverage for materials in transit is often:
- Limited to a specific dollar amount
- Restricted to certain transportation methods
- Conditional on proper documentation and security
If a shipment of custom windows is stolen from a truck, coverage depends on:
- Whether transit coverage is included
- Who bears responsibility under the contract (supplier vs contractor)
👉 Key point: Responsibility may fall on the party who “owns” the materials at the time of loss—not always the contractor.
2. On-Site Storage Liability
Once materials arrive at the job site, things get more complicated.
High-value items like:
- Windows and doors
- Electrical panels
- Appliances
- Copper wiring
are frequent theft targets on Canadian job sites.
Who Is Responsible?
Responsibility depends on:
- Contract terms (e.g., CCDC contracts)
- Insurance policy wording
- Whether materials have been installed or just stored
Typical scenarios:
| Situation | Likely Responsibility |
|---|---|
| Materials delivered but not installed | Usually contractor or site owner |
| Materials stored off-site | May not be covered unless declared |
| Subcontractor-supplied materials | Subcontractor may bear risk |
👉 Many disputes arise because parties assume coverage exists when it doesn’t.
Common Exclusions to Watch For
Builder’s risk policies in Canada often exclude:
- Poor storage practices
- Employee theft (may require separate coverage)
- Mysterious disappearance (without proof of forced entry)
- Off-site storage (unless specifically endorsed)
Always review:
- Policy limits for materials
- Sub-limits for theft
- Security requirements
Job Site Theft in Canada: A Growing Concern
Construction site theft is a persistent issue across Canada, especially in urban areas and rapidly developing regions.
Why theft happens:
- Valuable materials left overnight
- Minimal surveillance
- Easy resale of items like copper and appliances
Financial impact:
- Project delays
- Replacement costs
- Insurance premium increases
- Potential disputes between stakeholders
Best Practices to Reduce Risk
Mitigating risk isn’t just about insurance—it’s about site management and planning.
1. Secure Storage Solutions
- Use locked containers or cages for high-value items
- Install temporary fencing with controlled access
- Store materials indoors whenever possible
2. Just-in-Time Delivery
- Schedule deliveries closer to installation time
- Avoid long-term on-site storage
This reduces both theft risk and liability exposure.
3. Surveillance and Monitoring
- Install cameras with remote access
- Use motion detectors and alarms
- Post visible signage to deter theft
4. Inventory Management
- Maintain detailed delivery logs
- Photograph materials upon arrival
- Track high-value items separately
5. Contract Clarity
Clearly define in contracts:
- Who owns materials at each stage
- Who is responsible for insurance
- What happens in case of theft or damage
Using standard Canadian contracts (like CCDC) helps, but custom clauses are often needed.
6. Insurance Optimization
Work with a broker to:
- Confirm transit coverage
- Add off-site storage endorsements if needed
- Increase limits for high-value materials
- Understand deductibles and exclusions
Practical Example
Imagine this scenario:
A contractor orders $80,000 worth of custom windows. They are delivered to the job site but won’t be installed for two weeks. Overnight, the materials are stolen.
What happens next?
- If builder’s risk includes theft coverage → possible claim
- If storage conditions were inadequate → claim may be denied
- If contract assigns risk to supplier → dispute arises
👉 This is why insurance + contracts + site practices must align.
Final Thoughts
Builder’s risk insurance is essential for Canadian construction projects—but it’s not a catch-all solution.
Understanding material storage liability is critical because:
- Coverage varies widely
- Responsibility shifts between parties
- Theft and damage risks are real and costly
The most successful builders don’t just rely on insurance—they combine it with:
- Strong contracts
- Smart logistics
- Proactive security measures
